Subtitles issue on theme change

Hello,

I am very happy with your theme.

I tried to move the subtitles of the old theme to the subtitle area of your theme by querying the database.

I succeeded in this too.

My problem is that the subtitle byte account does not appear in the panel because it is wrong.

a:1:{s:11: “td_subtitle”;s:8: “subtitle”;}

As in the example above, the data that writes as “s:8” always writes the wrong byte length. This causes it not to be visible in the panel.

The site is in Turkish. I think the byte account in Turkish characters creates the problem. There are 55,000 news belonging to the old theme. It’s a 14 year old site and I don’t see any other care than moving them this way.

database uses utf8mb4.

I request your information and assistance in this regard.
